t IMPROVEMENT IN STREETCARS.

Specification forming part of Letters Patent No. 190,402, dated May 1,1877; application iiled April 21, 1877.

To all 'whom it may concern:

Be it known that I, GEORGE S. GLEMEN'rs, of Indianapolis, Indiana, haveinvented a new and useful Improvement in Street-Cars, of which thef'ollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, being made a part of this specification,in which- Figure l is a plan view of the running-gear of astreetcar withmy improvement attached. Fig. 2 is a section through y y of Fig. 1.

My invention relates more especially to street-cars, but may be appliedto other cars with advantage; and it consists, first, in the manner ofconstruction whereby the cars are capable of turning short curves withentire ease and safety.

To enable others skilled in the art to uu.- derstand and use myinvention, I will proceed to describe the exact manner in which Inh-avecarried it out.

In the drawings, A A represent the two circular frames, connected by thecoupling B, and provided with the slotted wings C C, for the support andintroduction of the wheels. On the inner and opposite segments of thetwo circular frames are attached the toothed bars D D, the teeth ofwhich bars mesh singly together, as shown in Fig. 1. It is evident, fromthis construction, that as the forward vaxle turns in a curve, the rearaxle is caused to adapt itself precisely to the same curve. The turningof the forward frame causes an exactly corresponding turn in the rearframe,

thus adapting it to the same curve. By this construction, not only mayshort curves in the track be turned without the thump orjar usuallycaused by turning curves, but turntables may be dispensed with, thusmaking a considerable saving of expense in the construction of tracks.On the wings C U are cast the bearings@ e for the short axles E, thewheels F playing through the slots ff.

In the front part of the circular traine I attach the lever Gr, reachingabove the loo r of, and entering to the platform, through a horizontalslot in the front, so that the driver can, by the pressure of his footon the lever, at any time apply the brake to the wheels. The lever Gr isconnected, by a rod or chain, directly with the brake-bar, and isreadily operated. by the driver, the horizontal slot in the front of theplatform giving tree play to the lever, as the direction of the car maychange.

Having thus explained my invention, what Iclaim as new, and desire tosecure by Letters Patent, is

The circular frames A A, provided with the toothed bars D l), incombination with the coupling B, Wings O C, short axles lil, and wheelsF, all coustructedto operate substantially as and for the purpose setforth.
